Anti-sliding pile for slope support
The invention discloses an anti-sliding pile for slope support. The anti-sliding pile comprises an anchoring rod, an outer bushing sleeved on the anchoring rod for being buried in the slope deeply and a screwing part which is in threaded fit with the upper end of the anchor rod and abuts against the upper end of the upper bushing. A lower taper expansion head expanding towards the end is arranged at the lower end of the anchoring rod, and at least three longitudinal notches are formed in the section of the outer bushing corresponding to the lower taper expansion head to form a lower expansion portion. The anchoring rod is sleeved in the outer bushing to form an overall anti-sliding pile structure, and accordingly, high anti-bending and anti-shearing capacities are provided, and the anti-sliding capacity is improved; besides, the lower taper expansion head at the tail end of the anchoring rod and the lower expansion portion form a self-lock structure, so that the anti-sliding pile is convenient and quick to mount, provided with a good fixing effect after being mounted, not prone to axial moving and capable of bearing high axial components produced by axial pulling force or slip mass slope staggering produced by slope expansion.
